A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the older nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide, NiO(OH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries typically have two to three times the capa. HistoryWork on NiMH batteries began at the -Geneva Research Center following the technology's invention in 1967. It was based on Ti2Ni+TiNi+x alloys and NiOOH electrodes. Development was sponsored. .
The negative electrode reaction occurring in a NiMH cell is H2O + M + e ⇌ OH + MHOn the positive electrode, nickel oxyhydroxide, NiO(OH), is formed: Ni(OH)2 +. .
When fast-charging, it is advisable to charge the NiMH cells with a smart to avoid , which can damage cells. The simplest of the safe charging methods is with a fix.
